Sacred space is by definition liminal space. Because we are not in control and not the center, something genuinely new can happen. Here we are capable of seeing something beyond self-interest, self-will, and security concerns. True sacred space allows alternative consciousness to emerge.
In prayer, I am learning to observe the silences between the words. I am learning that I don't have to fill the empty space because the space will eventually sing for itself. The waiting and listening and silence teach that the active work of prayer must be balanced by the humble acceptance of grace.
